Lipomas are common benign tumors usually detected on the torso, neck, upper thighs, and upper arms. However, they are rarely found in the parotid gland region. Because of their rarity at this site, they are not often considered in the differential diagnosis of parotid tumors. This report describes a rare case of a lipoma in the superficial lobe of parotid gland. A 71-year-old female patient admitted to our department complaining about swelling and pain in the posterior area of the left mandibular region since one month. Her medical history included mastectomy after breast CA fifteen years ago. Clinical examination revealed a smooth-surfaced, soft, and painful mass, with well-defined margins in the left mandibular region. Differential diagnosis of metastasis, inflammatory neck swellings, and benign salivary gland tumors were considered for the patient. Advanced imaging methods such as ultrasonography and contrast tomography revealed that the lesion was a lipoma of parotid gland. A surgical intervention under general anesthesia was planned for the removal of the mass; however patient refused the surgical treatment. Patient was placed on six-month periodic recall. This article reviews the radiographic appearance and differential diagnoses of lipoma in this rare location.

Lipomas are rarely found in the parotid gland region. Because of their rarity at this site, they are not often considered in the differential diagnosis of parotid tumors. The parotid lipoma is a slowly growing, asymptomatic, freely movable, soft mass. Preoperative diagnosis is generally difficult. We present a case of a slowly enlarging mass of the parotid region in a 44-year-old man that proved to be a lipomatous tumor of the parotid gland. We also review 42 other cases from the literature. Our patient's huge tumor was located in the superficial lobe of the gland, and a parotidectomy with preservation of the facial nerve was performed. There was no complication or recurrence of the tumor after a follow-up of 1 year.

Preoperative diagnosis of parotid tumors plays a crucial role in selecting and planning the surgical treatment. Ultrasound (US) with its modern techniques can contribute to the differential diagnosis of parotid tumors. This paper aims to achieve a comprehensive review of the ultrasound techniques used in the differential diagnosis of parotid tumors, based on the latest literature data. Considering that most parotid gland tumors are located in the superficial lobe, US is frequently the first imaging technique used for the diagnosis of parotid tumors. Sonoelastography can provide additional data on the elasticity of parotid tumors, but there is an overlap between malignant and benign parotid tumors parameters. Contrast-enhanced ultrasound adds value to conventional ultrasound and allows a more complete characterization of parotid tumors. Many authors have reported promising results using contrast-enhanced ultrasound in the differential diagnosis of parotid tumors. Multiparametric ultrasound with a careful and systematic approach usually allows an accurate differential diagnosis of parotid tumors.

Abstract Background We compared the ultrasound features, superb microvascular imaging (SMI) and micro vessel density (MVD) of pleomorphic adenoma (PA), Warthin’s tumor (WT) and basal cell adenoma (BCA) to explore the clinic value of SMI in differential diagnosis of benign tumors of parotid gland. Methods The vascular distributions and grade by color doppler flow imaging (CDFI) and SMI, as well as vascular index (VI) of 249 parotid gland masses from 217 patients were analyzed. Results The internal echogenicity of BCA are more homogeneous in comparing with WT and PA(P < 0.05). By SMI, the vascular distribution and vascular grade in PA were mainly peripheral (33.1%) and avascular (25.7%), Grade 1 (27.8%) and Grade 0 (25.7%). WT were mainly central (31.3%) and mixed distribution (34.9%), in Grade 3 (37.3%) and Grade 2 (36.2%). BCA was mainly peripheral (33.3%) and mixed distribution (33.3%), in Grade 2 (33.3%) and Grade 3 (33.3%). The overall detection rate of SMI for vascular Grade 2 and 3 was significantly higher than that of CDFI (P < 0.05). Both VI and MVD were lowest in PA, highest in WT (P < 0.001). The VI by SMI was correlated with MVD (P < 0.001). The correlation index between vascular distribution and grade by SMI and MVD were significantly higher than CDFI. Conclusion SMI can provide low-velocity blood flow information, which is helpful for the differential diagnosis of common benign tumors of parotid gland, and is expected to be more widely used.

Auriculotemporal Nerve

Plexiform neurofibromas are benign tumors that tend to occur in patients suffering from neurofibromatosis type 1 (NF-1). This report addresses a rare case where the tumor affected the parotid gland, deriving almost exclusively from the peripheral portion of the facial nerve. A 6-year-old male was referred to us complaining about a gradually enlarging swelling over the right parotid area. Imaging localized the lesion to the superficial lobe of the parotid gland, suggesting a neurofibroma. Cosmetic disfigurement and a functional deficit led us to perform complete surgical resection. Meticulous surgical dissection as well as auriculotemporal nerve origin made complete extirpation possible with almost zero morbidity and ensured alleviation of both aesthetic impairment and pain. This is the first case of an intraparotid PN in a pediatric NF-1 patient, which originated from branches of the auriculotemporal nerve and particularly from fibers of the autonomic nervous system. Radical surgical excision was decided according to established decision-making algorithms.

Abstract Objective Dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) histograms were used to investigate whether their parameters can distinguish between benign and malignant parotid gland tumors and further differentiate tumor subgroups. Materials and methods A total of 117 patients (32 malignant and 85 benign) who had undergone DCE-MRI for pretreatment evaluation were retrospectively included. Histogram parameters including mean, median, entropy, skewness, kurtosis and 10th, 90th percentiles were calculated from time to peak (TTP) (s), wash in rate (WIR) (l/s), wash out rate (WOR) (l/s), and maximum relative enhancement (MRE) (%) mono-exponential models. The Mann–Whitney U test was used to compare the differences between the benign and malignant groups. The diagnostic value of each significant parameter was determined on Receiver operating characteristic (ROC) analysis. Multivariate stepwise logistic regression analysis was used to identify the independent predictors of the different tumor groups. Results For both the benign and malignant groups and the comparisons among the subgroups, the parameters of TTP and MRE showed better performance among the various parameters. WOR can be used as an indicator to distinguish Warthin’s tumors from other tumors. Warthin’s tumors showed significantly lower values on 10th MRE and significantly higher values on skewness TTP and 10th WOR, and the combination of 10th MRE, skewness TTP and 10th WOR showed optimal diagnostic performance (AUC, 0.971) and provided 93.12% sensitivity and 96.70% specificity. After Warthin’s tumors were removed from among the benign tumors, malignant parotid tumors showed significantly lower values on the 10th TTP (AUC, 0.847; sensitivity 90.62%; specificity 69.09%; P < 0.05) and higher values on skewness MRE (AUC, 0.777; sensitivity 71.87%; specificity 76.36%; P < 0.05). Conclusion DCE-MRI histogram parameters, especially TTP and MRE parameters, show promise as effective indicators for identifying and classifying parotid tumors. Entropy TTP and kurtosis MRE were found to be independent differentiating variables for malignant parotid gland tumors. The 10th WOR can be used as an indicator to distinguish Warthin’s tumors from other tumors.

Malignant And Benign Tumors

The incidence rate of thyroid cancer is increasing, especially among young and middle-aged people. In most cases a malignant tumor can be diagnosed at the background of multinodular goiter. Differential diagnosis of malignant and benign tumors of the thyroid presents considerable difficulties. In this situation the decision on the extent of the surgical intervention seems to be important. In the article there are described features of the diagnosis and the choice of the surgical intervention for thyroid cancer associated with multinodular goiter. The morphological examination is the decisive method of diagnosis. The decision on the extent of the operative measure should be both individualized for each particular patient and proceed from the principles of oncological radicalism and functional effect.

Tomography Scan

Benign tumors of the salivary glands are varied and named after their cell type. They occur most commonly in the parotid gland, and the majority (approximately 80%) are pleomorphic adenoma. This benign tumor arises from the superficial lobe of the gland in approximately 80% of cases. Less commonly, the mass presents as a cheek mass overlying the masseter muscle, arising from the accessory parotid lobe. If the tumor arises from the deep lobe, it presents as a para-pharyngeal mass with a completely different clinical presentation. In this instance, the patient will complain of snoring and difficultly in swallowing. Physical examination will reveal a soft palate and tonsillar, diffuse bulge, which is firm in consistency. Malignant transformation is extremely rare. Ultrasonography, computed tomography scan and magnetic resonance imaging are the best imaging tools. Treatment is usually through superficial or total conservative parotidectomy, with preservation of the facial nerve.

CONTEXT: The minimal recommended surgical approach to parotid tumors is partial parotidectomy with resection of the superficial lobe of the gland. Histologic diagnosis prior to surgery is not possible, as incisional biopsies are contraindicated due to the possibility of facial nerve injury or incomplete tumor resection. Thus, the biopsies tend to be perioperative. OBJECTIVE: To compare the results of frozen section examination with the definitive pathological diagnosis. DESIGN: Accuracy study by retrospective analysis. SETTING: Head and Neck Surgery Service of Heliópolis Hospital, São Paulo, Brazil. SAMPLE: 153 cases of parotid gland tumors treated between 1977 and 1994. DIAGNOSTIC TEST: Frozen section and pathological diagnosis. MAIN MEASUREMENTS: Sensibility and specificity of the frozen section examination. RESULTS: Frozen section study diagnosed 19 (12.4%) malignant and 127 (83.7%) benign tumors. Sensitivity of the frozen sections for malignancy was 61.5% (95% CI 54 to 69%) and specificity was 98% (95% CI 94 to 100%), and this result is comparable to the literature. CONCLUSIONS: We consider that frozen section examination for salivary gland tumors is not sufficient on its own for deciding on the best management. Their interpretation must be correlated with clinical and intraoperative findings, in association with the surgeon's experience.

Hemangiomas are benign vascular deformities characterized by an increased proliferation and turnover of endothelial cells. They account for the majority of parotid gland tumors in infants but are rare in adults. Changes in blood flow dynamics within hemangiomas can cause stasis, thrombus formation and phleboliths. Tonsilloliths are calcifications occurring primarily within the palatine tonsillar crypts. We report the case of a large hemangioma of the parotid gland with multiple phleboliths and tonsilloliths in an adult, highlighting the clini cal and imaging features on panoramic radiography, Cone Beam Computed Tomography (CBCT), cervical ultrasound, Magnetic Resonance Imaging (MRI) and Doppler imaging. A 20-year-old woman presented, complaining of a painless swelling below her right ear. Panoramic radiograph showed multiple randomly distributed round-to-oval radiopaque structures overlying the right mandibular ramus. CBCT revealed several radiopaque structures in the right palatine tonsillar crypts. Cervical ultrasound exposed a large heterogeneous and predominantly hypoechogenic mass in the right parotid gland. MRI displayed a well-defined lesion in the right parotid gland extending into the parapharyngeal pre-styloid space, hypointense on T1 and hyperintense on T2, containing several nodules. The diagnosis was: large hemangioma of the right parotid gland extending into the parapharyngeal pre-styloid space, with multiple phleboliths and tonsilloliths. Propranolol was delivered, with periodic follow-up on Doppler images, showing a hemangioma size reduction. Standard radiographs can detect tonsilloliths and phleboliths but additional imaging modalities disclose the exact diagnosis and location of calcifications and the diagnosis, structure and extent of the vascular lesion. Tonsilloliths and phleboliths should be considered in the differential diagnosis of radiopaque masses involving the mandibular ramus. Hemangioma with phleboliths should be considered in the differential diagnosis of parotid tumors when numerous intraglandular calcification nodules are detected on radiographs.
